compact crash [@ nsThreadManager::GetIsMainThread(int*)] a very few 3.0b4pre. four 3.0pre - look to be the same person, perhaps during startup but bad stack, so perhaps a variation of bug 484550? http://crash-stats.mozilla.com/report/list?product=Thunderbird&version=Thunderbird%3A3.0pre&query_search=signature&query_type=exact&query=&date=&range_value=1&range_unit=weeks&do_query=1&signature=nsThreadManager%3A%3AGetIsMainThread%28int*%29 bp-b250a5f5-ee23-47ad-9639-b79412090920 0 libxpcom_core.dylib nsThreadManager::GetIsMainThread xpcom/threads/nsThreadManager.cpp:288 1 libxpcom_core.dylib NS_IsMainThread_P nsThreadUtils.cpp:124 2 libxpcom_core.dylib nsArrayConstructor xpcom/ds/nsArray.cpp:232 3 libxpcom_core.dylib nsComponentManagerImpl::CreateInstanceByContractID xpcom/components/nsComponentManager.cpp:1687 4 libxpcom_core.dylib CallCreateInstance nsComponentManagerUtils.cpp:170 5 libxpcom_core.dylib nsCreateInstanceByContractID::operator const nsComponentManagerUtils.cpp:210 6 libxpcom_core.dylib nsCOMPtr_base::assign_from_helper nsCOMPtr.cpp:150 7 thunderbird-bin nsMsgDBFolder::AutoCompact 8 thunderbird-bin nsMsgLocalMailFolder::EndMove mailnews/local/src/nsLocalMailFolder.cpp:2833 9 thunderbird-bin nsCopyMessageStreamListener::EndCopy mailnews/base/src/nsCopyMessageStreamListener.cpp:179 10 thunderbird-bin nsMsgProtocol::OnStopRequest mailnews/base/util/nsMsgProtocol.cpp:401

still a low grade crash, and still Mac-only. Crash comments was moving a message I deleted a message and Thunderbird crashed did a body search - deleted old messages that matched but were old and no longer needed - boom BTW - can someone please fix having to enter the Master Password TWICE when tbird starts? Deleting (move to Trash) an IMAP message. crash occurred when I tried to open another folder in a new window xref Bug 514481 - crash [@nsThreadManager::GetMainThread(nsIThread**)] [Mac]

I believe that several of these are mine. The crashes are not repeatable, usually a few weeks apart. My thunderbird is set up for imap IDLE processing, and I get the feeling that the crash is a race condition between background updates and my delete. Current build (3.0.4 has a bug preventing me from using it): Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.1.8) Gecko/20100227 Thunderbird/3.0.3 Here are some of my other crashes which may be related: http://crash-stats.mozilla.com/report/index/bp-d74aeb79-4904-4f03-b8a7-062ab2100322 http://crash-stats.mozilla.com/report/index/bp-e76c5396-d7e3-41e2-ab0f-1ace32100223 http://crash-stats.mozilla.com/report/index/bp-f09d010f-1115-4dfd-83c6-fb7222100120 http://crash-stats.mozilla.com/report/index/bp-b6b62432-c8ab-40dc-b523-e97c12091218 http://crash-stats.mozilla.com/report/index/bp-d055cb49-08c2-4d2b-9ba2-6e7312091202 These are my most recent crashes for 3.0.x (earlier ones are 3.0pre), and they are my only crashes.

Phil, do you crash if IDLE is disabled?

(In reply to comment #3) > Phil, do you crash if IDLE is disabled? I will disable IDLE and switch back to polling, but based on my track record it may take a few weeks to repeat (or not, being difficult to prove the negative).

I've had another crash that looks the same, had IDLE turned off. ID: 523a8ea3-224e-473f-a46c-171a72100504

And another, still with IDLE off. ID: bp-611f1977-897c-4acb-b050-be73f2100524 Seems to be not related to IDLE, am enabling it again unless further testing is requested.

Another crash with public release 3.1 (Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.4) Gecko/20100608 Thunderbird/3.1) bp-51b0b1b8-4231-4f85-a1b7-a1c402100701

> bp-51b0b1b8-4231-4f85-a1b7-a1c402100701 (Phil's) bp-f6fad5c3-b5b5-4991-a41d-c3bdb2101031 (different user I think) Does this really belong in XPCOM? Does it go at nsMsgMailSession::OnItemIntPropertyChanged or nsMsgMailSession::OnItemEvent ? most frequent comment is deleting last message in thread or folder. A striking similarity to Bug 410320 - Crash when deleting mail, if two windows for the mail are opened [@ nsMsgMailSession::OnItemEvent]

Phil doesn't see this anymore. And there are only version 3.x crashes. None for v5 or above
